ValueHandler (bool IsIncoming, MachineIRBuilder &MIRBuilder, MachineRegisterInfo &MRI) | |
virtual | ~ValueHandler ()=default |
bool | isIncomingArgumentHandler () const |
Returns true if the handler is dealing with incoming arguments, i.e. | |
virtual Register | getStackAddress (uint64_t MemSize, int64_t Offset, MachinePointerInfo &MPO, ISD::ArgFlagsTy Flags)=0 |
Materialize a VReg containing the address of the specified stack-based object. | |
virtual LLT | getStackValueStoreType (const DataLayout &DL, const CCValAssign &VA, ISD::ArgFlagsTy Flags) const |
Return the in-memory size to write for the argument at VA . | |
virtual void | assignValueToReg (Register ValVReg, Register PhysReg, const CCValAssign &VA)=0 |
The specified value has been assigned to a physical register, handle the appropriate COPY (either to or from) and mark any relevant uses/defines as needed. | |
virtual void | assignValueToAddress (Register ValVReg, Register Addr, LLT MemTy, const MachinePointerInfo &MPO, const CCValAssign &VA)=0 |
The specified value has been assigned to a stack location. | |
virtual void | assignValueToAddress (const ArgInfo &Arg, unsigned ValRegIndex, Register Addr, LLT MemTy, const MachinePointerInfo &MPO, const CCValAssign &VA) |
An overload which takes an ArgInfo if additional information about the arg is needed. | |
virtual unsigned | assignCustomValue (ArgInfo &Arg, ArrayRef< CCValAssign > VAs, std::function< void()> *Thunk=nullptr) |
Handle custom values, which may be passed into one or more of VAs . | |
void | copyArgumentMemory (const ArgInfo &Arg, Register DstPtr, Register SrcPtr, const MachinePointerInfo &DstPtrInfo, Align DstAlign, const MachinePointerInfo &SrcPtrInfo, Align SrcAlign, uint64_t MemSize, CCValAssign &VA) const |
Do a memory copy of MemSize bytes from SrcPtr to DstPtr . | |
Register | extendRegister (Register ValReg, const CCValAssign &VA, unsigned MaxSizeBits=0) |
Extend a register to the location type given in VA, capped at extending to at most MaxSize bits. | |

inlineoverridevirtual |
Materialize a VReg containing the address of the specified stack-based object.
This is either based on a FrameIndex or direct SP manipulation, depending on the context. MPO
should be initialized to an appropriate description of the address created.
